Natural gas rates to increase in Washington on Nov. 1

The higher costs for customers are due to last winter’s colder temperatures coupled with the 2018 gas pipeline explosion in British Columbia.

OLYMPIA, Wash. —

Natural gas customers in the state of Washington will start seeing higher energy bills beginning Nov. 1, according to the Washington Utilities and Transportation Commission (UTC).

On Thursday, the UTC approved rate adjustments ranging from 4-15% for Puget Sound Energy, Cascade Natural Gas, NW Natural, and Avista natural gas customers.

The higher costs for customers are due to last winter’s colder temperatures coupled with the 2018 gas pipeline explosion in British Columbia.
